BOTTLE-CAPPING MACHINE.

To all whom it may concern:

-Be it known that I, FRED G. MEYER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Bottle-Capping Machine, of which the following is a specification.

This invention relates to bottle capping machines and more particularly to manually operable machines forapplying crown caps to bottles.

It is the object of the invention to provide a simple and inexpensive mechanism whereby a crown cap may be quickly applied to a bottle without requiring either skill or training on the part of the operator.

' In attaining this object the invention contemplates a bottle supporting base, a standard rising therefrom, a plunger vertically reciprocatory in a head adjustable upon said standard, a head upon the plunger for engaging the crown cap and. forcing the same into engagement with the bottle when the plunger is'forced down, a cam and lever for forcing the plunger down, and a spring for effecting return motion of the plunger.

A preferred embodiment of the invention is illustrated in the accompanying drawing, wherein;

Fig. 1 is a view of the bottle capping machine in side elevation.

Fig. 2 is a horizontal sectional view of the same on line 22 of Fig. 1.

In these views, the reference character 1 designates a base, preferably metallic, and formed with holes 2 for receiving nails or like means for fastening said base to a table or other suitable support. Said base is provided upon its top surface with a boss 3 which is centrally recessed as indicated at 4. to form a seat for the bottle 5 which is to be capped. Said base is formed at one edge thereof with an integral upstanding lug 6 to which the lower end of a standard 7 is secured by a bolt or screw 8. Said standard is preferably formed by a wrought iron or steel bar such as is readily available and requires no machining. A head 9 is vertically adjustable upon said standard above the base 1, said head having a portion 10 slidably embracing the standard and adapted to be clamped thereto by a screw 10 and Specification of Letters Patent.

a portion 11 forming a slide bearing for the vertically reciprocatory plunger 12. The latter carries at its lower end a head 13 having therein the downwardly opening socket 14, proportioned to adapt the edge thereof to engage the flared skirt of a crown cap 15 to deflect said skirt inwardly to embrace an annular head 17 adjacent the mouth of the bottle on the down stroke of the plunger.

The down stroke of the plunger is effected by a cam 18, bearing upon the upper end of the plunger and having the integral actuating lever 19 projecting therefrom, said cam being mounted upon a bearing 20 formed as an upward extension of the member 11. Re

turn movement of the plunger is accomplished by a coiled spring 21 extending between lugs 22 and 23 formed integral respectively with the bearing 20 and the plunger head 18. In theposition of the parts disclosed in Fig. 1 the plunger 12 has been forced downwardly by the cam 18, thereby forcing socket 14 over the flared skirt of the cap to contract said skirt and engage the same with the head 17 of the bottle.

From the foregoing description of the invention the operation thereof is believed selfevident. It may be mentioned, however, that the adjustability of the head 9 upon the standard 7 serves to adapt the machine for use in capping bottles of various sizes. The provision of the recessed seat 4 for the bottle in the base of the machine insures a coaxial relation of the bottle and plunger so that no manipulation of the bottle is necessary to insure the cap being properly applied thereto.

Neither skill nor the exercise of any considerable strength is required in operating the machine, for which reasons and because of its low cost it is well adapted for use in the home.

Vhat I claim is:

A bottle capping machine comprising a base having an integral upstanding lug at one edge thereof, a standard formed of bar metal secured at its lower end to said lug and having an imperforate upper portion, a head adjustably clamped upon the upper portion of said standard and formed with a vertical slide bearing above said base and said plunger to actuate the same down:

ardly, a bottle capping member carriedby the lower end of said plunger, and a spring 'efiect thetup-sti oke of the plunger.

extending at one side of the bearing from point thereupon to said capping member to "linjestimony. whereof I sign this sp eific zi- 0n!, r
